GEBIET DER ERFINDUNGAREA OF INVENTION
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Übertragen trennender Kräfte auf ein Ziel.The The present invention relates to an apparatus and a method to transfer separating forces on a goal.
BESCHREIBUNG DER VERWANDTEN TECHNIKDESCRIPTION THE RELATED TECHNIQUE
Nach dem Stand der Technik existieren verschiedene Lasersysteme. Ein Festkörperlasersystem umfasst im Allgemeinen einen Laserstab zum Emittieren von kohärentem Licht und eine Stimulationsquelle zum Stimulieren des Laserstabs, damit er das kohärente Licht emittiert. Typischerweise werden Blitzlampen als Stimulationsquellen beispielsweise für Erbium-Lasersysteme verwendet. Die Blitzlampe wird von einem Blitzlampenstrom angetrieben, welcher eine vorbestimmte Impulsform und eine vorbestimmte Frequenz umfasst.To In the prior art, various laser systems exist. One Includes solid state laser system generally a laser rod for emitting coherent light and a stimulation source for stimulating the laser rod so that he is the coherent one Emitted light. Typically, flashlamps are sources of stimulation for example Erbium laser systems used. The flash lamp is powered by a flashlamp driven, which has a predetermined pulse shape and a predetermined Frequency includes.
Der Blitzlampenstrom treibt die Blitzlampe bei der vorbestimmten Frequenz an, um dadurch eine Ausgangslichtverteilung der Blitzlampe mit der im Wesentlichen gleichen Frequenz wie der Blitzlampenstrom herzustellen. Diese Ausgangslichtverteilung aus der Blitzlampe treibt den Laserstab an, damit er kohärentes Licht mit der im Wesentlichen gleichen vorbestimmten Frequenz wie der des Blitzlampenstroms herstellt. Das kohärente Licht, welches von dem Laserstab erzeugt wird, weist eine optische Ausgangsenergieverteilung über die Zeit auf, welche im Allgemeinen der Impulsform des Blitzlampenstroms entspricht.Of the Flashlamp current drives the flashlamp at the predetermined frequency to thereby output light distribution of the flash lamp with the in Substantially the same frequency as the flash lamp power. This output light distribution from the flashlamp drives the laser rod for it to be coherent Light of substantially the same predetermined frequency as which produces the flash lamp current. The coherent light coming from the Laser bar is generated, has an output optical energy distribution over the Time, which is generally the pulse shape of the flash lamp current equivalent.
Die Impulsform der optischen Ausgangsenergieverteilung über die Zeit umfasst typischerweise eine relativ allmählich ansteigende Energie, welche bis zu einer maximalen Energie hoch läuft, und eine nachfolgend über die Zeit abnehmende Energie. Die Impulsform einer typischen optischen Ausgangsenergieverteilung kann einen relativ effizienten Betrieb des Lasersystems bereitstellen, was einem relativ großen Verhältnis durchschnittlicher optischer Ausgangsenergie zu der durchschnittlichen Leistung entspricht, welche in das Lasersystem eingespeist wird.The Pulse shape of the output optical energy distribution over the Time typically involves a relatively gradual increase in energy, which goes up to a maximum energy, and one below about the Time decreasing energy. The pulse shape of a typical optical Output power distribution can be a relatively efficient operation of the Provide laser system, what a relatively large ratio average optical output energy equals the average power, which is fed into the laser system.
Impulsform und Frequenz nach dem Stand der Technik können für thermische Schneidvorgänge geeignet sein, bei welchen beispielsweise die optische Ausgangsenergie auf eine Zieloberfläche gerichtet wird, um ein Schneiden zu bewirken. Neue Schneidverfahren basieren jedoch nicht alle auf laser-induzierten thermischen Schneidmechanismen. Insbesondere richtet ein neuer Schneidmechanismus optische Ausgangsenergie aus einem Lasersystem in eine Verteilung zerstäubter Fluidpartikel, welche in einem Raumvolumen knapp oberhalb der Zieloberfläche angeordnet sind. Die optische Ausgangsenergie wechselwirkt mit den zerstäubten Fluidpartikeln, wobei bewirkt wird, dass sich die zerstäubten Fluidpartikel ausdehnen und elektromagnetisch induzierte Schneidkräfte auf die Zieloberfläche übertragen. Als Ergebnis der einzigartigen Wechselwirkungen der optischen Ausgangsenergie mit den zerstäubten Fluidpartikeln sind typische optische Ausgangsenergieverteilungs-Impulsformen und Frequenzen nicht besonders für ein optisches, elektromagnetisch induziertes Schneiden geeignet. Spezielle optische Ausgangsenergieverteilungen sind für ein optimales Schneiden erforderlich, wenn die optische Ausgangsenergie in eine Verteilung zerstäubter Fluidpartikel zum Bewirken eines elektromagnetisch induzierten Schneidens der Zieloberfläche gerichtet wird.pulse shape and prior art frequency may be suitable for thermal cutting operations in which, for example, the optical output energy on a target surface is directed to effect a cutting. New cutting methods However, not all are based on laser-induced thermal cutting mechanisms. Especially A new cutting mechanism aligns output optical energy a laser system into a distribution of atomized fluid particles, which arranged in a volume of space just above the target surface are. The output optical energy interacts with the atomized fluid particles, causing the atomized fluid particles to expand and transmit electromagnetically induced cutting forces to the target surface. As a result of the unique interactions of the optical output energy with the atomized Fluid particles are typical output optical energy distribution pulse shapes and frequencies not particularly for an optical, electromagnetically induced cutting suitable. Special optical output power distributions are for an optimal Cutting required when the optical output energy in one Distribution of atomized Fluid particles for effecting electromagnetically induced cutting the target surface is directed.

Teilchen, wie beispielsweise Elektronen, welche den Fremdstoffen zugeordnet sind, absorbieren Energie aus der einfallenden inkohärenten Strahlung und steigen in höhere Valenzzustände auf. Die Teilchen, welche auf metastabile Ebenen aufsteigen, verbleiben auf diesen Ebenen für Zeitspannen, bis beispielsweise Energieteilchen der Strahlung stimulierte Übergänge erregen. Die Stimulation eines Teilchens in der metastabilen Ebene durch ein Energieteilchen führt sowohl zu einem Abfall der Teilchen auf einen Grundzustand als auch zu einer Emission von doppelten kohärenten Photonen (Energieteilchen). Die doppelten kohärenten Photonen können durch den Laserstab zwischen Spiegeln an gegenüberliegenden Enden des Laserstabs schwingen, und sie können andere Teilchen auf der metastabilen Ebene stimulieren, um dadurch nachfolgende doppelte kohärente Photonenemissionen zu erzeugen. Dieser Prozess wird als Lichtverstärkung durch stimulierte Emission bezeichnet. Mit diesem Prozess tritt ein Paar doppelter kohärenter Photonen mit zwei Teilchen auf der metastabilen Ebene in Wechsel wirkung, um dadurch vier kohärente Photonen zu ergeben. Nachfolgend kollidieren die vier kohärenten Photonen mit anderen Teilchen auf der metastabilen Ebene, um dadurch acht kohärente Photonen zu ergeben.particles such as electrons associated with the foreign substances are, absorb energy from the incident incoherent radiation and go up in higher valence on. The particles which rise to metastable levels remain on these levels for Time periods until, for example, energy particles of the radiation excite stimulated transitions. The stimulation of a particle in the metastable plane through an energy particle leads both to a drop of the particles to a ground state as well to an emission of double coherent photons (energy particles). The double coherent Photons can through the laser rod between mirrors at opposite ends of the laser rod swing, and they can stimulate other particles at the metastable level to thereby subsequent double coherent Generate photon emissions. This process is called light amplification termed stimulated emission. With this process, a couple enters double coherent Photons interact with two particles at the metastable level thereby four coherent To give photons. Subsequently, the four coherent photons collide with other particles at the metastable level, thereby making eight coherent To give photons.

Gesichtspunkt der vorliegenden Erfindung umfasst die optische Ausgangsenergieverteilung
Wie oben stehend beschrieben, wird der Halbwertsbreitenbereich von einer Anfangszeit, bei welcher die Amplitude zunächst oberhalb der Hälfte der Peak-Amplitude ansteigt, bis zu einer Endzeit definiert, bei welcher die Amplitude ein letztes Mal während der Impulsbreite unter die Hälfte der Peak-Amplitude fällt. Der Halbwertsbreitenwert ist als die Differenz zwischen der Anfangszeit und der Endzeit definiert.As is described above, the half-width range of one Start time, where the amplitude is above half of the first Peak amplitude increases, to an end time defined at which the amplitude one last time during the pulse width is less than half the peak amplitude drops. The half-width value is the difference between the start time and the end time defined.
Der Ort des Halbwertsbreitenbereichs entlang der Zeit-Achse befindet sich hinsichtlich der Impulsbreite näher am Beginn des Impulses als am Ende des Impulses. Der Ort dieses Halbwertsbreitenbereichs liegt vorzugsweise innerhalb ungefähr der ersten Impulshälfte, und bei einem Beispiel liegt er besonders bevorzugt innerhalb ungefähr des ersten Drittels des Impulses entlang der Zeit-Achse. Es sind gemäß der vorliegenden Erfindung auch andere Orte des Halbwertsbreitenbereichs möglich. Die Anfangszeit des Halbwertsbreitenbereichs tritt vorzugsweise innerhalb der ersten 10 bis 15 Mikrosekunden auf, und besonders bevorzugt innerhalb der ersten 12,5 Mikrosekunden ab der führenden Flanke des Impulses. Die Anfangszeit kann jedoch entweder früher oder später innerhalb des Impulses auftreten. Die Anfangszeit wird vorzugsweise innerhalb ungefähr des ersten Zehntels der Impulsbreite erreicht.Of the Location of the half-width range is located along the time axis in terms of pulse width closer to the beginning of the pulse as at the end of the impulse. The location of this half-width range is preferably within about the first half of the pulse, and in one example, it is most preferably within about the first third of the momentum along the time axis. It is in accordance with the present invention Other locations of the half-width range possible. The beginning time of the Half width range preferably occurs within the first 10 to 15 microseconds, and more preferably within the first 12.5 microseconds from the leading edge of the pulse. However, the start time may be either earlier or later within the pulse occur. The start time preferably becomes within about the first Tenth of the pulse width reached.
